-.Sh NAME
-.Nm ng_sppp
-.Nd sppp netgraph node type
-.Sh SYNOPSIS
-.In netgraph/ng_sppp.h
-.Sh DESCRIPTION
-An
-.Nm ng_sppp
-node is a
-.Xr netgraph 4
-interface to the original
-.Xr sppp 4
-network module for synchronous lines. Currently
-.Xr sppp 4
-supports PPP and Cisco HDLC protocol.
-An
-.Nm ng_sppp
-node could be considered as an alternative kernel mode ppp
-implementation to
-.Xr mpd ports +
-.Xr ng_ppp 4
-and as an alternative to
-.Xr ng_cisco 4
-node.
-While having less features than mpd +
-.Xr ng_ppp 4 ,
-it is significantly easier to use in the majority of simple configurations
-and allows the administrator to not install the mpd port.
-With
-.Nm ng_sppp
-you don't need any other nodes, not even an
-.Xr ng_iface 4
-node.
-When an
-.Nm ng_sppp
-node is created, a new interface appears which is accessible via
-.Xr ifconfig 8 .
-.Nm ng_sppp
-node interfaces are named
-.Dv sppp0 ,
-.Dv sppp1 ,
-etc.
-When a node is shutdown, the corresponding interface is removed
-and the interface name becomes available for reuse by future
-.Nm ng_sppp
-nodes.
-New nodes always take the first unused interface.
-The node itself is assigned the same name as its interface, unless the name
-already exists, in which case the node remains unnamed.
-The
-.Nm ng_sppp
-node allows drivers written to the old sppp interface to be rewritten using the
-newer more powerful
-.Xr netgraph 4
-interface and still behave in a compatible manner without supporting both
-network modules.
-.Pp
-An
-.Nm ng_sppp
-node has a single hook named downstream. Usually it is connected directly to
-a device driver hook.
-.Pp
-.Nm ng_sppp
-nodes support the Berkeley Packet Filter (BPF).
-.Sh HOOKS
-This node type supports the following hooks:
-.Pp
-.Bl -tag -width abcdefghijklmnop
-.It Dv downstream
-The connection to the synchronous line.
-.El
-.Sh CONTROL MESSAGES
-This node type supports the generic control messages, plus the following:
-.Bl -tag -width foo
-.It Dv NGM_IFACE_GET_IFNAME
-Returns the name of the interface corresponding to this node in a
-.Dv "struct ng_iface_ifname" :
-.Bd -literal -offset 4n
-struct ng_iface_ifname {
-  char  ngif_name[NG_SPPP_IFACE_NAME_MAX + 1];
-};
-.Ed
-.El
-.Sh SHUTDOWN
-This node shuts down upon receipt of a
-.Dv NGM_SHUTDOWN
-control message.  The associated interface is removed and becomes available
-for use by future
-.Nm ng_sppp
-nodes.
-.Pp
-Unlike most other node types and like
-.Xr ng_iface 4
-does, an
-.Nm ng_sppp
-node does
-.Em not
-go away when all hooks have been disconnected; rather, and explicit
-.Dv NGM_SHUTDOWN
-control message is required.
-.Sh EXAMPLES
-For example, if you have
-.Xr cx 4 device, you could run PPP over it with just one command:
-.Pp
-ngctl mkpeer cx0: sppp rawdata downstream
-.Pp
-Now you have sppp0 interface (if this is a first sppp node) which can be
-managed via
-.Xr ifconfig 4 as a usual network interface,
-or via
-.Xr spppcontrol 8 as a sppp interface.

-.Xr ifconfig 8 ,
-.Xr ngctl 8,
-.Xr spppcontrol 8
-.Pp
-For complex networking topologies you may want to look at
-.Xr mpd ports .
-.Sh HISTORY
-The
-.Nm ng_sppp
-node type was implemented for
-.Fx 5.0 .
-It was included to the system since
